ANCHOR ARRANGEMENT.

Specification of Letters Patent.

A Patented Apr. 5, 1921.

Application filed May 1, 1920. Serial No. 378,031.

To all whom it may concern:

Be it known that 1, Ar Tnnvon Jonas, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Anchor Arrangements, of which the following is a specification.

This invention relates to anchor arrangements.

General speaking, there are two types of anchors, one known as the stock anchor, in which the shank of the anchor has no relative movement with respect to its crown or head, and the other one known as the stockless anchor, in which the shank has a relative movement with respect to its crown or head. It is to the latter type of anchor that my invention has particular applica tion.

The main advantages of the stockless type of anchor over the other type are the ease of stowing away the anchor on the ship, and primarily in that the stockless type of anchor has two flukes for simultaneously engaging and hooking into the bottom of the sea for holding firmly.

The one disadvantage of the stockless anchor is that the flukes thereof are a little slow in hooking into the bottom of the sea after reaching same.

Accordingly, one object of this invention is to overcome this disadvantageous feature in a simple and eflicient manner.

' Another object is to provide a 'stockless anchor adapted to meet all of the requirements for successful use.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which- Figure 1 is'a front elevation'of an anchor embodyingmy invention;

Fig. 2 is a side elevation of the same 'anchor; i

Fig. 3 is a fragmentary side elevation of the same anchor, a portion of the head being in section, and showing the shank in vertical position with the flukes at an angle of 45 with respect thereto, one of the two positions taken bythe parts of the anchor as the anchor-is being lowered and raised; and,

Fig. at is a side elevation of the same an chor, a portion of the head being shown in Section, and showing the shank locked to the head of the anchor for causing a quick gripping action of the anchor when passed into engagement with the bottom of the sea, the position shown being that which is assumed after the head of the anchor has reached the bottom of the sea and the shank having moved downwardly a certain predetermined amount from its vertical position.

7 The various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings,.

it will be noted that I have shown a stockless type of anchor including a head 10 and a shank 11, the latter being pivotally connected to the former by means of trunnions 12 extending laterally from the shank and cooperating with bearing portions within the head. The inclined walls 13 ofthe head form stops for limiting the relative movement between the shank 11 and head 10. Preferably the maximum relative movement between said parts is about 90, there being a 45 swinging movement to either side of a central alined position of the head and shank. The head 10 is provided with two fiukes 14: which are the ground engaging or gripping members. The head is also proyidecl with oppositely and laterally extendlng projections 15 at the base of the flukes to cause the fiukes to assume a digging or gripping position when the head of the anchor rests upon thebottom of the sea, as shown in Fig. 4. However, as mentioned hereinabove, the stockless type of anchor is a little slow in digging into and gripping the bottom of the sea in spiteof the inclination given to the flukes by theprojections 15, as

shown in Fig. 4. To overcome this disadand accordingly,

: causing the projecting bottom of the sea As shown in Fig. 4 of the drawings, the shank 11 of the anchor is locked to the head 10 thereof by one of the two locking members 16. Said locking members are pivotally connected to the head of the anchor intermediate the shank and; the flukes, and preferably as near thebase of the shank as possible to occupy the minimum amount of space and to facilitate stowing away of the anchor. To )ivotally mount the locking members 16 in t e head 10 of the anchor, said locking members 16 are provided with trunnions 17 which cocperate with suitable bearing portions carried by the head. Each ofsaid locking members has a locking projection 18 which extends laterally inwardly from the main part of the locking member toward the shank to a point where said locking pro jectionsextendinto the path of movement of cooperating locking lugs 19 carried on opposite sides of the shank 11. As shown in Fig. 4 of the drawings, one of the locking projections 18 is in locking engagement with one of the lugs 19 for holding the shank and head in a relative fixed position. \Vith the parts as shown in this figure, the shank 11 is prevented from moving clownwardly relatively'to the head of the anchor, the weight of the shank and .also the weight of the chain 20, or at least a portion thereof, and its clevis 21 connectingit to the shank 11 act in amanner to cause a relatively quick gripping or hooking action of the flukes into the bottom ofthe sea, this being especially true in view of the fact that the weight'of the shank, clevis and chain act through a relatively long lever arm. These locking members 16 operate automatically to lockand unlock the shank and head, and preferably are gravity actuated, having weighted portions 22 for causing the automatic locking and unlocking action. As shown in Fig. 3 of the drawings, it will be noted that the locking, projection 18 is out of locking engagement with its associated locking lug 19 on the shankll, the shank llbeing-in a verti cal position and the fiukes arranged at an angle of 45.with respect thereto, this'being the position of the parts when the anchor is being loweredand raised.

Assuming that the cred, the head thereof finally reaches-tho and gradually tips over from the 45 angle to and beyond a horizontal positionyas shown in'Fig. 4. During this tipping action the locking member 16, which is to take effect, swings from an inoperativeposition into the operative locking position at the critical point due to the weighted portion22-of the locking member, portion'18 of the locking member to fall'in front ofthe associated locking lug 19 on the shank. for looking the head and shank'together' for the anchor is being lowpurpose hereinabove set forth. When the anchor is raised from the position shown in Fig. 4, the shank gradually moves toward a vertical position, as shown. in Fig. 3, and at a critical point the, locking projection 18is caused to pull out of locking engagement with the locking lug 19 due to'the action of the weighted portion 22 of the locking member for automatically causing the head and shank to be unlocked with respect to each other. The locking members 16 are pre vented from moving progressively beyond a locking position by a tail portion 23 which engages a portion of the head. It will be understood that the locking and unlocking actions are as eilective on one side as they are on the other.

It is my intention to coverall m0difica tions of the invention falling within the spirit and scope of the following claims.

I claim:

1. A stockless anchor including a head, a shank movably connected thereto, and means carried by'said head cooperating with said shankfor locking said head and shank in a given relative position for creating a gripping leverage causing a quick gripping action of the anchor.

2-. A stockless anchor including a head, a shank movably connected thereto, and means carried by said head cooperating with said shank for automatically locking said head and shank in a given relative position for creating a gripping leverage causing'aquick gripping action of the anchor. V V

A. stockless anchor including a head, a

connected thereto, and gravshank movably ity actuated means carried by said head cooperating with said shank for' locking said head and shankin a given relative position '10 for creating a gripping leverage causing a quick gripping action ofthe anchor. y 4. A stockless'anchor including a head, a shank movably connected thereto, and movablymounted members carried by'said head and mounted upon opposite sides of said shank for cooperating with the latter to lock the head and shank in a given relative position for creating a gripping leverage causing aquick gripping action of the anchor. 5; Astockless anchor including a head, a shank movably connected thereto, and oppositely extending members carried by said head for engaging portions of said shank in given relative positions for creating a a. quick gripping causing a quick gripping action of the anchor.

7. A stockless anchor including a head, a shank movably connected thereto and having a projection thereon, and a member pivotally connected to the head of said anchor and having a portion for engaging said of April, 1920.
